Use your skill and knowledge to place various scientific lengths in order of size. Can you judge the length of objects with sizes ranging from 1 Angstrom to 1 million km with no wrong attempts?
All in a Jumble
My measurements have got all jumbled up! Swap them around and see if you can find a combination where every measurement is valid.
Sizing Them Up
Can you put these shapes in order of size? Start with the smallest.
Up and Across
Experiment with the interactivity of "rolling" regular polygons, and explore how the different positions of the dot affects its vertical and horizontal movement at each stage.
How Far Does it Move?
Experiment with the interactivity of "rolling" regular polygons, and explore how the different positions of the red dot affects the distance it travels at each stage.
Take Your Dog for a Walk
Use the interactivity to move Pat. Can you reproduce the graphs and tell their story?
Rolling Around
A circle rolls around the outside edge of a square so that its circumference always touches the edge of the square. Can you describe the locus of the centre of the circle?
Watch the Clock
During the third hour after midnight the hands on a clock point in the same direction (so one hand is over the top of the other). At what time, to the nearest second, does this happen?

Four vehicles travel along a road one afternoon. Can you make sense of the graphs showing their motion?
Uniform Units
Can you choose your units so that a cube has the same numerical value for it volume, surface area and total edge length?
Where Am I?
From the information you are asked to work out where the picture was taken. Is there too much information? How accurate can your answer be?

Measure for Measure
This article, written for students, looks at how some measuring units and devices were developed.
Eclipses of the Sun
Mathematics has allowed us now to measure lots of things about eclipses and so calculate exactly when they will happen, where they can be seen from, and what they will look like.
